The stems will start to grow roots if they get buried. Several plants can do this. Hilling potatoes is pretty common practice, this is just taking it to an extreme
You can safely go about 3-4 boxes high for potatoes without risking rot, as long as you’ve got good drainage and don’t overwater - the soil at the bottom shouldn’t stay sopping wet.
Is there a risk of lower down potatoes rotting? How tall can you reasonably go
As long as the soil is able to drain through it and not sit there for weeks, should be fine.
So, burying the green part completely doesn’t hurt them?

I don’t suspect so - I’ve never tried it, but I would really like to.
I’m also not sure how tall it can get - depends on your growing season and the plant’s lifecycle
